SPECIFICATION forming part of Letters Patent N o. '771,443, datedOctober 4, 1904. Application filed March 7, 1904. Serial No. 196,9l'7.No model.)

To all whom, it nuy concern:

Be it known that I, MAX PERKIEWICZ, a subject of the Emperor of Germany,residng at Ludwigsberg, near Moschin, Germany, have invcnted new anduseful Improvements in Coating Bricks and in Apparatus Therefor, of

which the following is a specification.

This invention relates to improvements in coating bricks and inapparatus therefor.

,fiour mixture) substances which prevent putrefaction. As examples ofsuch substances 1 may mention carbolic acid lysole, sublimate, andnitric acid. Furthermore, I have found that aluminium sulfate, tannicacid or salts of chromium can be added to the coating material withapproximately the same result. The application of the liquid coating tomolded bricls which are not in the form of a continuous slab and have ashaped surface is not possible with apparatus as heretofore made, and Iuse for this purpose the apparatus hereinafter described, andillustrated in the accompanying drawings, in which- Figure 1 is a sideview of the apparatus; and Figs. 2, 3, and 4 are views of a detailhereinafter described.

The apparatus comprises. a chain conveyer arranged at an inclination tothe horizontal and above which is located a distributing-box a for thecoating material. The distributingbox a is provided with fineperforations or slits at the bottom. Below the upper part of theconveyer is fitted the collecting-trough which receives the superfluouscoating material as it drops from the brick.

The operation of the apparatus is as t'ollows: The bricksm, laid uponthe inclined conveyer, pass under the distributing-box a, and theirupper surfaces are covered with the liquid coating. The material is 'edinto the distributing-boX (a from the tank f through the pipe IL, thesaid pipe /L being provided with a valve 7,' and the tank f beingfurnished with a stirring device g. The su perfiuous liquid coatingwhich drops from the bricls runs into the trough n, whence it flows awaythrough the overflow o into the well p. Fromthis well it can be raisedby a suction or pressure pump (Z to the feed-tank f. The slats b serve'or guiding the conveyer-chatin. In some cases the superfluous liquidwhich fiows from the collecting-trough n through the pipe 0 isadvantageously passed through a sieve before it reaches the well inorder to free it of impurities. F urthermore, the said well p can beprovided with stirring mechanism.

In order to be able to coat bricks which have projections or recesses atan angle to the longitudinal aXis of the conveyer, it must bc arrangedthat the coating material can run ofi' the bricks without collecting inthe recesses therein. This is efi ected by arranging the axes of theconveyer at an inclination, so that the coating or glazing appled to thebricks cannot only flow to the lower end of the conveyer, but can alsoquickly escape laterally. The lateral escape of the coating can,however, be effected by any other suitable meansas, for example, thatillustrated in Figs. 2, 3, and 4, which show a form of conveyer havingconcave-shaped supports. This arrangement has the advantage that thebrick can be placed directly upon the supports at a greater or lessinclination, according to the size of the projecting or recessedportions which it possesses.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to bc performed, I declare thatwhat I claim is- 1. The process of coating bricks which consists inmovng the bricks progressivcly and maintaining them in an inclinedposition transversely with respect to their direction of movement andapplying a liquid compound to said bricks from a point above their lineof travel, while said bricks are in motion, substantially as described.

2. The process of coating bl'ClS which consists in moving the bricksprogressively and IOO maintaining them in an ang'nla' position bothtmnsversely and longitudinally With respect to the direction of theirmovement, to permit them to dmin and applyinga liquid compound to saidbi'ieks While moving and in such inelned position, substantially asdescribed.

MAX PERKIENVICZ.
